Ah. I figured I missed something. Thanks!

The KOP regulators have the capability of regulating higher pressure than 60PSI if you set them to.

No.

Some manufactures offer optional outlet pressure ranges, but I do not see that on this cut sheet.

Should not have passed with >60 outlet pressure.
IMHO, not an inspector.

Hi Guys,

The max pressure rating for this device is 145 psi.
This is sold under the NITRA label so I can't share the original manufacturers data sheet with you.
I'll put in a request to get the NITRA spec sheet updated.

Comments on posts:

(Jeff Pahl - Been Long time! How ya doing!)

#7: "And the spec sheet only says that it regulates from 15-120 PSI." It regulates between those values - the max rating is 145.

#12: R66G - This really only applies to the primary regulator which HAS to be the KOP regulator (and is limited to 5-50psi). These should only be used DOWNSTREAM of that. Just like all the other regulators we typically use. Yes, I know the rules don't explicitly say that - we are talking to FIRST about the wording of that rule because it doesn't make any sense as stated...

#13 "Is it worth using these type of fittings ..." Oh yeah ... Space savings, weight savings, mount them anywhere, totally worth it. And again - these would not be used as the primary regulator right up next to the compressor.

This IS a PRV type regulator (relieves excess downstream pressure)

And while we are at it ...

The original post only shows two of the parts offered as inline. There are a bunch more folks need to be aware of:

Pressure Indicators: (PMU14A, PMU14G) Green and Orange - Has a little pop-up indicator that pops up when the system has 30+ psi in it. An awesome way to tell if the system is pressurized at a glance

Shut Off Valves - 2 and 3-way shut off valves - the 3-way valves relieve downstream pressure so you can shut off a subsystem and release pressure at the same time. Very handy. (HVU14-2, HVU14-3)

These are also available in lockable versions.

These don't pass R66, unless we ignore the parenthetical "(specifically "needle valves")". I wanted to use some last year and was shot down by the GDC:

Q34
Q.Is a quick release valve, such as the one sold by Bimba (part number 1BQEV), considered a flow control valve, and thus a legal pneumatic component per Rule 77 (F)?
A.Quick Exhaust Valves are not included on the list of permitted items in R77.

R77(F) is largely identical to this year's R66(F) except for this year's addition of "passive" and the parenthetical. So unless the GDC's interpretation has greatly changed, quick exhaust valves were illegal this year.

Mind you, I'd love if they were legal for the obvious speed increases. So if you're petitioning the GDC to update the regulator part of R66, you might want to add that as well.

I'm going to be emailing Rick Folea on Monday to ask him that. It just so happens that it's a small world, and a long time ago in another place and time we used to work together
